The course contains 24 online tests with 265 exercises, over 300 PowerPoint slides, all necessary reference materials, and comes in two flavors: a Demo Version and Full Version.
Demo Version has a limited functionality but can be accessed by anyone. Please keep in mind that guests cannot take online tests; a regular user account is needed to do that; see FAQ.
On the other hand, Full Version is available by default to anyone who buys Nailing 1Z0-808 (both download link page and thank-you email will contain the so-called Enrollment Key that unlocks the course).
The latest version of Nailing 1Z0-808 on amazon.com already has this key on page 6; for those of you guys who bought older copies, there’s only one option: please contact me, and I’ll register you for this course manually.
